B.G 2.62 and 63
ध्यायतो विषयान् पुंसः सङ्गस्तेषूपजायते। सङ्गात् सञ्जायते कामः कामात् क्रोधोऽभिजायते॥६२॥
क्रोधाद्भवति सम्मोहः सम्मोहात् स्मृतिविभ्रमः। स्मृतिभ्रंशाद् बुद्धिनाशो बुद्धिनाशात् प्रणश्यति ॥६३॥
When the person dwells on material topics, he develops attachment in them. From attachment springs desire. From that desire comes forth the anger. Anger results in the inability to discriminate. Loss of discrimination results in the distortion of memory. The distorted memory destroys the knowledge. He perishes from the destruction of knowledge.
Gīta Bhāshya 2.62 and 63
'sammōhaḥ' - desire to do the prohibited action. 'smr̥ti vibhramaḥ' - distortion of memory that aids one to resist doing prohibited action. 'buddhināśaḥ' - destruction of the knowledge that enables one to recognize defects fully. 'vinaśyati' - obtains hell.
रागादिदोषकारणमाह परिहाराय श्लोकद्वयेन। सम्मोहः अकार्येच्छा। तथाहि मोहशब्दार्थ उक्तः उपगीतासु-
The defect that arises due to passion (rāga) and its solution is elaborated in these two verses. 'sammōhaḥ' means desire to do the prohibited action. Same meaning is given for the word 'mōha' in Upa-gīte:
"मोहसंज्ञितं। अधर्मलक्षणं चैव नियतं पापकर्मसु।"
इति।
'moha' is said to be of the characteristics of unrighteousness and is always fixed in sinful deeds.
-states thus.
तथा चान्यत्र-
Similar meaning is given in other places as well:
"सम्मोहोSधर्मकामिता"
इति।
'sammōha' is the desire for 'adharma', i.e. unrighteousness.
-states testimonial.
स्मृति विभ्रमः प्रतिषेधादिबुद्धिनाशः। बुद्धिनाशः सर्वात्मना दोषबुद्धिनाशः। विनश्यति नरकाद्यनर्थं प्राप्नोति। तथाह्युक्तम्-
'smr̥ti vibhramaḥ' - means destruction of the knowledge that aids one to control and not to do prohibited action. 'buddhināśaḥ' - means destruction of the knowledge to recognize defects fully. 'vinaśyati' - means he obtains hell and such undesirables. Therefore it is said:
"अधर्मकामिनः शास्त्रे विस्मृतिर्जायते यदा। दोषादृष्टेस्तत्कृतेश्च नरकं प्रतिपद्यते॥"
इति ॥ ६२, ६३ ॥
When one desire unrighteousness, forgetfulness of the scriptures arises. Having lost the ability to recognize wrong, they obtain hell.
- states testimonial.
Gīta Tātparya 2.62 and 63
'saṁmōhā' - means wrong knowledge
संमोहात् मिथ्याज्ञानात् । ज्ञातमपि अन्यथा स्मर्यते। वाक्यार्थानामन्यथा स्मरणात् निर्णीतं ज्ञानमपि नश्यति ॥ ६२,६३ ॥
'saṁmōhāt' - means wrong knowledge, i.e. even after understanding thinking otherwise. Because of mind's attention on something else, knowledge to decipher the meaning of the sentence is lost.
